What Size Am I in Shein?

It's the question every first-time Shein shopper asks: what size am I in Shein? The short answer is that you're probably one to two sizes larger than your US size. Shein uses Asian sizing that's calibrated to a smaller body frame, so a US Small becomes a Shein Medium or Large, and a US Medium becomes a Shein Large or XL. But the exact conversion depends on the category — shoes are different from tops, and swimwear is different from jeans. Our converter above gives you your specific Shein size for every category. Just select your gender, choose a category, pick Shein as your store, and enter your usual US size. In seconds, you'll see your Shein size plus your size at four other popular stores for comparison. No more guessing, no more returns.
